California fires could reach record levels in 2008

An unusually early and dangerous fire season has hit California, where at least 33 fires burning over a total of 190,000 acres are active, according to the Interagency Fire Center. The fires were sparked over the weekend when an unusually far southward-moving storm system brought numerous thunderstorms to central and northern California. Over 8,000 lightning strikes hit the region. Most of these strikes were not accompanied by rain, since a very dry atmosphere at low levels caused much of the thunderstorm rain to evaporate before reaching the surface. The lightning strikes ignited an unusual number of fires, due to exceptionally dry vegetation in California. This year, the state experienced its driest spring season (March-April-May) since record keeping began in 1895, and much of the state is in moderate to severe drought.


Figure 1. Visible satellite image from NASA's Aqua spacecraft on Monday, June 23, 2008, showing smoke from hundreds of wildfires sparked by lightning in California. The red regions show where the satellite's sensor detected fires burning. The smoke has created air pollution levels in excess of the federal standards for fine particulate matter (PM2.5) over much of California's Central Valley. Image credit: NASA.

The forecast
With the dry season only beginning, it could be a record fire year in California. Even before last weekend's lightning storms, California had already seen an unusually large number of destructive wildfires, according to CalFire--90,000 acres had burned, compared to 42,000 acres during the same period last year. It is not unusual for large portions of the state to receive no rain at all in July and August, such as occurred last year (Figure 2). The jet stream typically moves far enough north in summer that the migrating low pressure systems that bring California most of its rain only hit the northernmost portions of the state. With high fuel levels due to a century of misguided fire suppression efforts, moderate to severe drought gripping the state, no rain in sight for months to come, and an above-normal chance of warmer than average temperatures forecast this summer for the state by NOAA's Climate Prediction Center, expect a record fire season in California.


Figure 2. Observed precipitation over California during 2007. Much of the state received no rain at all during July and August, which is a common occurrence. A little bit of thunderstorm activity did make it into the easternmost portion of the state, thanks to moisture flowing north-westward from the Arizona Monsoon. However, the Sierra Mountains block this moisture from reaching the central and western portions of the state. Image credit: NOAA.

Tropics
It's quiet in the tropical Atlantic. There are no threat areas to discuss, and none of the models are forecasting tropical storm formation in the next seven days. Beyond a week from now, the GFS is hinting that the region off the coast of Africa could see some development, but it is still probably too early for this too occur, despite warmer than average sea surface temperatures in the region.

Oh Well...my Java won't let me get satellite loops from the SSD Tropical Satellite Imagery, so I can't confirm if there is a surface low, with this CATL ''disturbance''...

Well, if we can talk about fires, floods, tornados, et al, why can't we talk about the north pole too? I actually think it's interesting, since the last genuinely warm period up there nobody from our culture was around measuring things.

if this area of convection is not a wave ---it was not mentioned in the 8.05 tropical disussion then it is a pertabation from the ITCZ

I notice there isn't a tropical wave associated with that convection near 35W. It's probably just some ITCZ convection that will be gone by later today or tomorrow.

Morning all

Nice flare up of convection around 7N, 34W. Some slow development is even ''possible'' here, as SSTs are hot enough, not to much dry air around, (good outflow pattern to the NW), and there's an anticyclone futher west of the wave...the only inhibiting factor is that it's to far south...

Near 8 N and 36 W is a nice spin...shear is under 20 knots....

that is right people like to stick to tradition. hurricane ivan was a typical example for hurricane to form so far out in the alt and south of 10deg N. this system is in the same position as ivan except it is juns and ivan was in sept. climatology is a guide but not gospel

989.

That doesn't matter. You see, climo says that development shouldn't occur until about August out there because conditions aren't normally favorable. But currently, shear is low and SSTs are above average and there is low dust. So the factors are there. Just because Climo says it can't happen doesn't mean and won't. Look at Hurricane Bertha in 1996. It happened there.

morning
an area of disturbed weather is associated with a tropical wave few hunderd miles sw of the cape verde islands. there appears to be a mid level circulation near 6n 35w. there is also good outflow from the nw of the system. shear and sst is favourable in the area and the system should gradually organised as it moves westward. the QS nor the ASCAT were not available and will have to wait a little later to see if a surface is low forming with the system

Well i guess everyones gone to bed.
One question has anyone heard from Floodman? I think he had some test done the other day, he was on here but wasn'tfeeling to good. I was just wondering.

Pat- I really hope we never see another 2005, I live in Lower Alabama, well Mobile right outside of it. It was he?? over here and i just can't imagine in my head how bad it was for you all. When they showed that one man on tv with his kids and his wife said to save the kids and let her go or however it went, I cried so bad and the super dome it was just sickining. We had it pretty rough over her to. Our shop went under water. it was bad.

area of convection (95E) located near 12.2N 120.2W or 870 NM southwest of Cabo San Lucas, Mexico. Recent animated METSAT Imagery indicates consolidating convection over a low level circulation center. A ASCAT PASS depicts a well defined low level circulation center with 25-30 knot unflagged weasterly winds south of the circulation. Upper elvel analysis shows low vertical wind shear and good diffluence aloft with an upper level trough to the north further enhancing poleward outflow.

Maximum sustianed winds near the center is 22-27 knots with a minimum sea level pressure of 1008 MB. Due to the improved consolidation of the low level circulation and good upper level support, the potential for this disturbance to form into a significant tropical cyclone within the next 24 hours is UPGRADED TO GOOD.
